Obviously these members may'assume a great variety of formsandmay consist of separate pieces of'metal secured to the face of thescraper. It will be seen, however, that the arrangement illustratedprovides a scraper which will positively direct the oil in its pathtoward theinterior of the wrist pin'during either the inward or outwardmovement of the piston.

The operation of' the device described above will be readily apparentfrom the description of parts. It presupposes. a suitable film of oil onthe cylinderwall in the path of travel of the'oil scra er'. This oil maybe fed to the cylinder w l in any suitable manner as through an oil ductfrom some suitable type of 'lubricator, (not shown).

' As the piston reciprocates in the cylinder the scraper will remove acertain amount of oil from the cylinder wall, andthiswill be forced orprojected intothe central oil receiving recess14 in the scraper. {Itwill imniediately be carried therefrom by the pipe 12 to the interior ofthe hollow wristpm '7, thence through ducts bushing or bearing. 7 Thelubricating device herein described late the wrist pin and illustratedmay be applied equally well "to either a'vertical or horizontaleng1ne.,It

' is-obvious that the device is also applicable to many ,other types ofreciprocating mechanisms,'such as cross heads and the like,

' wherever it is possible to dispose 'thescraper adjacent a surfacesupplied with lubricant.

I claim: y a 1. In an engine having a cylinder, :1 piston therein and abearing in said piston, a lubrieating meansfor sa d bearing comprising alubricant collector carried by said piston and a conveying means betweensaid collector and said bearing and relatively inclinedproject- Members17 serve to gather oil adapted to operate one at a time, to collectlubricant on alternate strokes of said piston. 2. In an engine, acylinder, a piston a piston. pin lubricator comprising a mem r aving aface portion conforming substantially to aportion ofthe cylinder walland adapted to be so plied with lubricant therefrom, said *mem erincluding lubricant distributing means, and being carried by said pimonda plurality of lubricant-ira- ;pe,lling;,projectionsdisposed in angularrelation on the face of said member, and adapted. to reflect and todeliver lubricant to said distributing means during the travel of saidpiston-i11 each direction, and irrespective of piston position.
